COTTON-GIN, SCALE, AND PRESS.

:SPBCEFICATION forming part of Letters Patent No. 359,914, dated March 22, 1887.

Application filed April 9, 1886. Serial No. 198,358. (No model.)

To (LZZ whom it may concern.-

Be it known that I, Prrr EDWARD WILL- IAMSON, of Washington, in the county of Vilkes and State of Georgia, have invented a new and useful Improvement in a Portable- I Figurel is aperspective view of my improved machine. Fig. 2 is a side view of the same. Fig. 3 is an end view of the forward end of the press with the cotton-gin removed, and Fig. 4 is alongitudinal vertical sectional view taken on line a: as, Fig. 3, of the drawings.

The same letters of reference indicate corresponding parts in all the figures.

Referring to the several parts by letter, A represents the frame which supports the sev-- eral parts of my improved machine, the said frame being supported on road-wheels B, of ordinary construction, which arrangement renders the machine portable, and enables it to be conveyed readily from place to place. In

the middle and rear portion of this frame A is supported the compression-box C, which rests upon its side, as shown, its end D forming the bed-piece, against which the most pressure is exerted in compressingthe bale of cotton. A cross-piece, E, extends horizontally across theforward end of the compression-box,

and is formed with a central aperture, F, in-

which is seated a metallic sleeve, G, having the flanged inner end, H.

I indicates a metallic sleeve, which fits loosely within the stationary sleeve Gand has secured concentrically to its outer end a bevel-wheel,

with a screw-thread and passing through the central aperture, K,of the bevel-wheel J, above mentioned, the said aperture being formed with ascrew-thread which fits the screw-thread of the follower-rod. f

To the forward end of the frame A, to each side of the center thereof, are secured in suitable bearings, P, the inner ends of short trans, verse shafts Q Q, which carry at their inner extremities the bevel-pinions R, both of which mesh with the bevel-wheel J, and the outer portions of these transverse shafts are journaled inthe forward ends of centrally-pivoted adj ustable levers S, the rear ends of which may be raised or lowered and secured in their adjust-ed positions.

To the outer end of each transverse shaft Q is secured a frictionwheel, T, which, when the rear ends of the centrally-pivoted levers S are raised, bear against smaller friction-wheels, U, secured on the projecting outer end of a shaft, V, which is journalcd transversely in bearings at the forward end of the frame A. This transverse shaft'is provided with two band-pulleys, around one of which, W, passes the belt from the engine which supplies the motive power,

while around the second pulley, Z, passes a. belt, H, which conveys'motion to and operates the cotton-gin X. This cotton-gin X is supported at the'forward upper end of the main frame A, which is extended forward for the requisite distance, and the platform which supports the operative mechanism of the gin is about on a level or in the same horizontal plane with the upper side of the compressionbox 0. 1

I do not wish to confine myself to the par ticular form of gin shown in the accompanying drawings, as I can employ any gin, and I make no claim for the specific construction thereof.

Immediately to the rear of the compressor Yof the cotton-gin is supported, preferably on the cross-piece E, the scales A, which may be of any suitable, construction and which serve to weigh the lint as it passes from the compressor Y before entering the compressionbox 0. An upper transverse cross-piece of the mainframe A extends between the scales A and the receiving-doors of the box 0. The box 0 is provided in its upper side with the large hinged doors B, which admit the cotton rod of suitable thickness bent at right angles at its upper and lower ends, as shown; and a removable cross-piece, G, also extends beneath and gives additional support to the lower hinged door, D, the ends of this cross-piece resting upon the lower side pieces of the main frame A. a

The operation of my combined cotton-gin, scales, and press is as follows: The machine having been hauled to the requisite point in the field, and the rear ends of the centrally pivoted levers S having been secured in their lowered positions to throw the friction-wheels T out of gear with the friction-wheels U on the transverse shaft V, the belt from an engine is passed around the band-pulley W of the shaft V, and as the said shaft rapidly rotates itwill, through the belt H, operate the cotton-gin X on the forward upper portion of the main frame; and the cotton, after passing through thesaid gin, falls from the compressor Ythereof upon the scales A, by means of which the cotton may be weighed before entering through the doors B in the upper side of the box Ointo the interior of the said box to the rear of the follower. When the requisite amount of cotton has been placed in the box, the hinged doors B are closed, and a locking-bar, I, having one of its sides slightly beveled, is inserted beneath the upper side pieces of the frame, bearing firmly upon the doors B,which it serves to hold tightly and firmly in their closed position. The doors of the box 0 being now closed and locked, the rear end of one of the centrally-pivoted levers S is raised, so as to throw the large friction-wheel, T, which it controls, into contact with the small frictionwheel, U, at that end of the long transverse shaft,V, thereby rotating the short transverse shaft, Q, and the pinion at its inner end, and also the bevel-wheel, which meshes with the said pinion. As this bevel-wheel rotates it will work the screw threaded compressorrod, which passes through its central screwthreaded aperture, back, thereby forcing the follower M back and pressing the mass of cotton in the box 0 into a solid bale at the rear end of the said box. hen the bale has been thoroughly compressed, the rear end of the centrallypivoted lever, which was previously BEST AVAlLABLE c the cross piece G is removed from beneath the lower hinged door of the box and the hale allowed to fall upon the ground. To retract the follower, the opposite centrally-pivoted lever is raised at its rear end, to throw the friction-wheel on that side of the machine into contact, which, as will be readily seen, rotates the bevel-wheel J in the opposite direction, thereby retracting the follower to the forward end of the compression-box,when the centrally-pivoted lever is automatically lowered, throwing the friction-wheel onthat side out of gear involuntarily, when the operation above described is repeated. The forward end of the follower-rod may be provided with a transverse stop-pin, J, to limit the play of the follower-rod.

From the foregoing description, taken in connection with-the accompanying drawings, the construction and operation of my invention will be readily understood. I

It will be seen that my improved machine is simple in construction, while at the same time it is very efficient in its operation. The machine may be conveyed to any part of the field, being portable, and the cotton taken in its natural state at one end of the machine will be ginned, weighed, compressed, and delivered in the form of a tied bale, readyfo'r shipment, at the other end of the machine.

Having thus described myinventiomwhat I I claim, and desire to secure by Letters Patent, is

1. An apparatus of the kind described, comprising a gin, the press-box having an inlet or receiving opening, the scales arranged adjacent said opening, and the compressors arranged between the scales and the gin, substantially as set forth.

2. The combination of the shaft V, having friction-wheels v v, the threaded follower-rod, the gear J, having a threaded opening fitting said rod, a bearing for gear J, the transverse shafts Q, having gears at their inner ends meshing with gear J, bearings P for the inner ends of said shafts, friction-wheels T, secured on the outer ends of shafts Q and arranged to be engaged by wheels 1), the levers S, pivoted between their ends and provided at one end with bearings for the shafts Q,and means for securing the opposite ends of said levers, substantially as set forth.

3. The combination of the main frame, the follower having the screw-threaded rod, the gear J, the transverse shafts having their inner ends meshed with gear J and their outer ends providedwith gears 'l, movable supports for said outer ends, and the shaft V, having gears 12, arranged to be engaged by gears T, substantially as set forth.
